Value Of Coefficient Of Friction Between Steel And Rubber

The friction force can be calculated as.

Value of coefficient of friction between steel and rubber.

Showing the concept of coefficient of friction. Static friction is friction between two or more solid objects that are not moving relative to each other. For example static friction can prevent an object from sliding down a sloped surface. For rubber on tarmac close to 1 0.

The coefficient of static friction typically denoted as μ s is usually higher than the coefficient of kinetic friction. The making of steel involves many processes and stages. A car with mass 2000 kg drives with speed 100 km h on a wet road with friction coefficient 0 2. The friction coefficient between the object and the surface is 0 62.

Example car braking friction force and required distance to stop. However it is possible to find tables in the literature for friction coefficients between various materials. For polished oiled metal surfaces less than 0 1. Static and kinetic coefficient of friction.

Where μ s is the coefficient of static friction and μ k is the coefficient of kinetic friction. The coefficient of friction is the ratio of a force to a force and hence has no units. The coefficient of static friction for steel is around 0 6 0 15 and the coefficient of kinetic friction is around 0 09 0 6. The value of μ s is generally higher than the value of μ k for a given combination of materials.

F f 0 62 100 lb 62 lb 1 lb 0 4536 kg. Typical values for the coefficient of friction when sliding is occurring i e. Coefficients of friction between materials are best determined through testing. The basic raw materials are coal iron ore limestone and various chemicals.

For glass on glass 0 4.
